Supply Chain Scheduling Using a Transportation System Composed of Vehicle Routing Problem and Cross-Docking Approaches
Authors
Abstract:
This study considers a combination of cross-docking and vehicle routing problem (VRP) approachesto transport raw material and parts in a supply chain. The supply chain is composed of some supplierswhich are spread in different geographical zones and multiple shared vehicles with different speedsand capacities for transporting orders from the suppliers to a manufacturer. After proposing amathematical model of this new problem, a developed version of genetic algorithm based on apsychological theory, named Reference Group Genetic Algorithm (RGGA) is used to solve theproblem. The originality of this research is proposing a new method in integrated production andtransportation scheduling in supply chain by combination of cross-docking and VRP approaches,presenting the mathematical model of the problem and adapting RGGA to solve it. To evaluateRGGA performance, we develop a genetic algorithm proposed for the nearest problem in literatureand compare these two algorithms. Moreover, RGGA results are compared with optimum solutionsby some low size test problems. The result shows the good performance of RGGA.

Multi-echelon distribution networks are quite common in supply chain and logistics. Deliveries of multiple items from factories to customers aremanagedby routing and consolidating shipments inwarehouses carrying on long-term inventories. On the other hand, cross-docking is a logistics technique that differs from warehousing because products are no longer stored at intermediate depots. Instead, ...

In cross docking strategy, arrived products are immediately classified, sorted and organized with respect to their destination. Among all the problems related to this strategy, the vehicle routing problem (VRP) is very important and of special attention in modern technology. This paper addresses the particular type of VRP, called VRPCDTW, considering a time limitation for each customer/retai...

In this paper we address the VRPCD, in which a set of homogeneous vehicles are used to transport products from the suppliers to customers via a cross-dock. The products can be consolidated at the cross-dock but cannot be stored for very long as the cross-dock does not have long-term inventory-holding capabilities. The objective of the VRPCD is to minimize the total traveled distance while respe...
